Yes, it's possible. People do it everyday. My husband and I (pre-Covid) walked to work daily, ~30 minutes, and have done so for years now. Get yourself appropriate winter clothing and boots and you'll be fine.
Every major firm I talked to said that 2020 was their most profitable year ever. Students, associates, and partners were busier than ever. Surprisingly good news from the industry. Wonder if we'll see salary raises for summers/another increase in pay scale soon?
